Description
Technical Field
[0001] This utility model belongs to the field of reclamation engineering technology, and relates to a drainage outlet, specifically a high-efficiency drainage outlet with a filter screen that can prevent silt blockage. Background Technology
[0002] Dredging and reclamation are the main methods for the development, improvement, and maintenance of ports and waterways, as well as important methods for island and reef construction and rapid land reclamation. During the construction process, dredgers need to transport the water, silt, and other mixed materials generated during dredging to the designated reclamation area through dredging pipelines. Then, foundation treatment measures are adopted to reduce the moisture content of the reclamation soil to meet the bearing capacity standards, thereby giving it greater utilization value.
[0003] Drainage outlets are crucial facilities for discharging water from reclamation areas, reducing mud loss and effectively protecting the environment. Currently, drainage outlets come in various forms, including gate-type, buried-pipe, and overflow weir-type outlets, all of which are used to varying degrees in reclamation projects.
[0004] Many current drainage outlets have numerous shortcomings. Some are constructed in a rudimentary manner simply to save costs, resulting in the following problems: First, improper installation leads to excessively high concentrations of discharged water, causing excessive sediment loss, resulting in not only economic losses but also environmental pollution. Second, many drainage outlets still use reinforced concrete structures for their foundations and main bodies, which are not only costly but also cannot be reused. Third, they cannot prevent the accumulation of debris, which also pollutes the environment and may cause debris to clog the drainage outlets with the water flow, affecting drainage efficiency. Fourth, many drainage outlets require frequent manual dredging after becoming clogged, which is time-consuming and labor-intensive.
[0005] Of course, people are now working to improve these shortcomings. Regarding silt filtration, for example, the patent announcement CN203559402 U discloses a silt-proof curtain for drainage outlets, comprising several fixed rods arranged equidistantly and connected by a curtain body. Each fixed rod has a fixing bolt at its top, and two anchor cables are connected to the top of each end of the fixed rod, forming a certain angle between them. The fixed rods are inserted into the foundation to unfold the curtain body, and the anchor cables are used to tighten the curtain and stabilize the fixed rods. The curtain body is strong, corrosion-resistant, effectively filters silt, and has a long service life. This silt-proof curtain has a simple structure, is easy to manufacture, and can block silt from the drainage outlet, preventing silt pollution of the water near the outlet. However, due to the different particle sizes of silt, fine sand, medium-coarse sand, and small stones, without stratified interception, the curtain is easily clogged, reducing drainage efficiency.
[0006] Regarding water level regulation, for example, patent publication number CN 206859239 U discloses a cofferdam spillway, including a spillway pipe and a spillway tank. The spillway tank includes a first frame, a top plate on the top side of the first frame, and a spillway hole on the top plate. The spillway pipe is vertically located on the top plate and communicates with the spillway hole. A cavity is formed between the second frame and the first frame, and a spillway gate is installed in the cavity. The technical problem this patent aims to solve is to provide a cofferdam spillway with a simple structure that allows for real-time observation and adjustment of the spillway height. However, ordinary wooden gates are not stable enough under the impact of water flow. Although gates composed of multiple steel gates have high stability, manual operation is difficult when adding or removing gates, requiring a lot of manpower.
[0007] Regarding the prevention of landfill debris, for example, patent CN 204199309 U discloses an embedded drainage outlet, including a base slab cast from plain concrete, a trapezoidal cavity, a drainage pipe located on the upper rear side of the base slab, and multiple partition walls located within the trapezoidal cavity. Slots are provided at the rear edges of the partition walls and on the rear sides of both inner sides of the trapezoidal cavity, with a steel mesh installed in front of the slots. This embedded drainage outlet can block landfill debris, and the overall structure is stable. However, this drainage outlet only has one layer of steel mesh to protect larger landfill debris and floating debris; it cannot effectively intercept many smaller gravel and silt, leaving them at the drainage outlet, which not only pollutes the environment but also causes certain economic losses.
[0008] Therefore, in order to overcome the shortcomings of the existing technology, it is necessary to develop a new type of high-efficiency drainage outlet with a filter screen that can prevent silt blockage. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0034] In view of the shortcomings of existing technologies, this utility model provides a high-efficiency drainage outlet that can filter and intercept floating objects, gravel, silt and sand in the cofferdam, and has a device for quickly shaking and cleaning the filter screen to prevent filter hole blockage.
[0035] like Figure 1 and 2 As shown, the high-efficiency drain outlet with filtration and anti-clogging function of this utility model includes a main housing 1. The main housing 1 serves as the main frame structure and stands within the reclamation area.
[0036] The main body 1 has a protective fence 2 at the front entrance, a support frame 5 in the middle, and a drain pipe 6 at the rear.
[0037] The protective fence 2 is mainly made of steel bars and is used to intercept large-volume landfill waste and large floating objects.
[0038] Preferably, such as Figure 7 As shown, a slot 11 is provided on each side of the front entrance of the main body 1. The two sides of the protective fence 2 are slidably connected to the two slots 11. In this way, the protective fence 2 is installed in the slots 11 at the front entrance of the main body 1, which is highly stable and will not be washed away by water flow. Moreover, it is convenient to install and remove the protective fence 2.
[0039] The lower half of the support frame 5 is provided with a filter screen frame 3 that can slide up and down relative to it, and the upper half is equipped with a rapid shaking device 4. The rapid shaking device 4 is connected to the upper end of the filter screen frame 3, thereby driving the filter screen frame 3 to shake up and down rapidly, so as to achieve a shaking cleaning effect on the filter screen frame 3.
[0040] The filter screen 3 can filter and intercept stones, silt, and other debris in the reclamation area, reducing the loss of soil and thus minimizing economic losses while protecting the environment. Figure 3 and 4 As shown, the central main body of the filter frame 3 is a steel wire filter 31. The steel wire filter 31 is the main component for filtering mud, sand, and other soil. The steel wire filter 31 is installed inside the outer frame 33. A pair of connecting and fixing plates 34 are provided on the top of the outer frame 33. The connecting and fixing plates 34 are connected to the rapid shaking device 4. Two upper and lower fixing sleeves 36 are welded to the back of the outer frame 33. A bearing axle 37 is inserted into each fixing sleeve 36. A rolling bearing 35 is installed at each end of the bearing axle 37. The rolling bearing 35 extends into the track groove 53 to facilitate vertical movement.
[0041] Preferably, the outer frame 33 has two rows of evenly distributed bottom plate holes 32 in its frame base plate. The bottom plate holes 32 are mainly used to reduce the water flow resistance when the rapid shaking device 4 shakes and cleans the filter screen frame 3.
[0042] The main function of the rapid shaking device 4 is to provide the filter frame 3 with the mechanical energy for rapid up-and-down shaking, so as to shake off the attached substances and clean and unclog the filter pores. Figure 5 and 6 As shown, the rapid shaking device 4 includes a drive motor 42. The drive motor 42 is mounted on a motor base 41. The motor base 41 is mounted on the upper half of the support frame 5. The shaft of the drive motor 42 drives a small pulley 43 to rotate. The small pulley 43 drives a large pulley 45 to rotate via a belt 44. The large pulley 45 is connected to an eccentric disc 48 via a transmission shaft 46. The transmission shaft 46 is fitted inside two seated bearings 47. The seated bearings 47 are mounted on the motor base 41. The eccentric disc 48 is connected to an eccentric bearing 49 via an eccentric connecting shaft 410. The outer shell of the eccentric bearing 49 is connected to one end of a transmission connecting rod 411. The other end of the transmission connecting rod 411 is connected to a bearing 412. The bearing 412 is connected to the upper end of the filter frame 3 via a pin 413. In this way, the rotational kinetic energy generated by the drive motor 42 is converted into mechanical energy that enables the filter frame 3 to shake rapidly up and down.
[0043] The support frame 5 serves as a mounting platform for the rapid shaking device 4 and provides a sliding track for the filter screen frame 3, preventing the filter screen frame 3 from being dispersed by the water flow. Figure 7 and 8As shown, the upper half of the support frame is provided with a crossbeam 51, and the lower half has a track groove 53 on each of its two sides, with the lower half fixed inside the main housing 1. The filter screen frame 3 is installed in the lower half of the support frame 5, and its two sides respectively cooperate with the two track grooves 53.
[0044] Preferably, the outer sides of the support frame 5 are bolted to the top of the main housing 1 via three-wing support bases 52. Thus, the three-wing support bases 52 welded to the outer side of the support frame 5 can be bolted to the main housing 1, and the outer steel frames on both sides are welded to the inner wall of the main housing 1, further improving stability when operating in water.
[0045] The drain pipe 6 is a steel pipe connecting the drain outlet to the outside, serving as a water conveyance channel for the outward discharge of water from the reclamation area. Preferably, the main housing 1 has an outlet hole at its rear, and the drain pipe 6 is connected to the outlet hole.
[0046] When the high-efficiency drainage outlet with filtration and anti-clogging function of this utility model is in use, the water flow in the reclamation area and the mud, clay, floating garbage, and other materials it carries enter the drainage outlet. First, the outermost protective fence 2 intercepts larger reclamation waste, floating boulders, and other waste materials. The water flow after being intercepted by the protective fence 2 and the remaining soil it carries continue to flow into the main tank 1, and then pass through the filter screen 3. The steel wire filter 31 on it can block and filter media such as gravel, spherical clay, and coarse mud and sand, thereby ensuring that the water discharged from the reclamation area retains mud and other soil to meet the drainage standards, which not only reduces economic losses but also protects the environment.
[0047] When the high-efficiency drain outlet with filtration and anti-clogging function of this utility model is used for a long time, the steel wire filter screen 31 will inevitably become clogged, thus affecting the drainage efficiency. At this time, the rapid shaking device 4 can be turned on. After the rapid shaking device 4 is turned on, the rotational kinetic energy generated by the drive motor 42 drives the small pulley 43 connected to the motor to rotate, thereby driving the belt 44 to move. The rotation of the belt 44 further drives the large pulley 45 to rotate. The rotation of the large pulley 45 further drives the eccentric wheel 48 to rotate through the transmission of the eccentric connecting shaft 46. Then, the rotation of the eccentric wheel 48 drives the eccentric shaft 49 connected to the eccentric connecting shaft 410 to revolve around the eccentric wheel, further driving the transmission connecting rod 411 connected to the eccentric bearing 49 to move up and down. This causes the filter screen frame 3 connected to the lower end of the transmission connecting rod 411 to shake up and down rapidly, thereby achieving the shaking and cleaning effect of the steel wire filter screen 31, clearing the blockage of the filter holes and restoring the drainage efficiency.
[0048] To prevent damage caused by rapid movement and water flow impact of the filter screen frame 3 in the water, track grooves 53 are provided on both inner sides of the support frame 5. These grooves control the up-and-down movement of the filter screen frame 3 within the grooves 53, preventing lateral swaying. Simultaneously, to avoid excessive water flow resistance generated when the filter screen frame 3 vibrates up and down, several round holes 32 are provided in the bottom plate in contact with the water flow, reducing energy loss due to resistance. This utility model's high-efficiency drain outlet with filtration and anti-clogging function can filter the water flow in the reclamation area while clearing blockages, offering high drainage efficiency and safer and more convenient operation than manual cleaning.
[0049] This utility model features a high-efficiency drainage outlet with filtration and anti-clogging function, employing a dual protection system of protective fence and filter screen frame. This effectively intercepts garbage, floating debris, gravel, and silt within the reclamation area, protecting the main equipment from impact while being more economical and environmentally friendly. Simultaneously, to prevent small gravel, silt particles, and clay balls from clogging the filter screen frame's mesh, a rapid shaking device is installed at the top of the filter screen frame. This device mechanically shakes the filter screen frame up and down at high speed, dislodging blockages to prevent affecting drainage efficiency, making it safer and more convenient than manual flushing. Furthermore, the filter screen frame's base plate has two rows of evenly spaced holes, significantly reducing water flow resistance during the rapid shaking device's cleaning process, making the device more energy-efficient. Finally, the support frame's installation design not only serves as a platform for the rapid shaking device but also, through the cooperation of its track grooves and the bearing rods on the back of the filter screen frame, ensures that the filter screen frame is not deformed by water flow during up-and-down shaking cleaning and reduces friction during vertical movement.
[0050] The above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
